- Anodic materials play a key role in the development of Li-ion batteries, as they influence their overall performances. Demand for improved energy and power densities, enhanced safety, and reduction in environmental impact have driven the attention toward progressive use of alternative materials with respect to state-of-the-art graphite. Developing advanced anodes requires a clear understanding and full exploitation of their underlying electrochemical mechanisms (e.g., Li insertion, Li-alloying, and conversion reactions). Nanostructured anode materials can help in achieving this goal and addressing issues to enable alternative candidates beyond graphite. The impact of nanomaterials on the development of Li-ion battery anodes is here discussed through a two-fold perspective focused on the performances enhancement and critical assessment of practical electrochemical energy storage applications of industrial relevance. A summary of the requirements to realize advanced anodes is provided at the beginning of the chapter, while geometrical aspects and dimensionality of nanostructures, together with their influence on the electrochemical properties of anodic materials and corresponding electrodes, are examined in the subsequent sections. The advantages and disadvantages of nanostructured anode materials are also discussed in detail, followed by examples of rational electrode design and composites for the fabrication of advanced nanostructured anodes. Finally, various anode materials are considered for these purposes and examples of 3D micro-battery anodes are also included.
